The student will use relations and functions to model number relationships.
Linear Equations and Graphs
Resources cannot be aligned to this standard, browse sub-standards to find lessons.
Calculate the slope of a line using a graph, an equation, two points or a set of data points.
Use the slope to differentiate between lines that are parallel, perpendicular, horizontal, or vertical.
Interpret the slope and intercepts within the context of everyday life (e.g., telephone charges based on base rate [y-intercept] plus rate per minute [slope]).
